Quick answer: There is no deadline to start a small business retirement plan. You can begin the process any month of the year. But plans generally take effect on a set calendar, and for many Central Pennsylvania employers the practical question in October is whether the team has the right plan on January 1: a first plan, a simpler plan, or an upgraded plan with features like a Roth option. Deciding in the fall is what makes a clean January start possible. PAC Financial in Harrisburg walks owners through the whole calendar in one 20 minute conversation: (717) 564-6400, ext. 181.
Every October, a specific kind of conversation happens in shops, offices, and job trailers across Dauphin, Cumberland, Lancaster, Lebanon, and York counties. An employee, usually a good one, asks the owner some version of: do we have a retirement plan here? And the owner, usually a good one, says some version of: I keep meaning to look into that. Just as often now, the question comes from owners who already have a plan: we have had the same plan for years, is it still the right one?
October happens to be National Retirement Security Month, a designation the United States Senate has endorsed through bipartisan resolutions. That makes this a fitting time to look into both questions for real. Fewer than 60 percent of workers at small companies have access to retirement benefits, per the U.S. Bureau of Labor Statistics National Compensation Survey from March 2025. Meanwhile, about 94 percent of small business owners say a retirement plan is important for attracting, retaining, and engaging employees, per a 2025 Ubiquity Retirement + Savings survey of 1,000 owners. Those two numbers sitting next to each other are the whole story. Owners know it matters. Most just have not gotten the calendar explained to them.
Is there a deadline to start a small business retirement plan?
No. This surprises people. You can call an advisor in February, June, or the week before Thanksgiving and begin building a plan. There is no date on the calendar after which a business is locked out.
What the calendar does control is when a plan takes effect and when certain housekeeping has to happen. A SIMPLE IRA, one of the most common starting points for businesses with 100 or fewer employees, generally takes effect on a date between January 1 and October 1 of a given year. Employees generally receive notice of the plan 60 days before they start participating. None of that is hard. It is simply sequential, which is why the owners who want the right plan running on January 1 tend to be the ones who picked up the phone in the fall.
| Your situation | Key date | What it means |
|---|---|---|
| No plan today, want one someday | None | Start the conversation any month. There is no deadline to begin. |
| No plan today, want one running January 1 | This fall | Decide in October or November so the 60 day employee notice lands cleanly before a January start. |
| Have an older plan, want modern features like a Roth option | November 2 | A provider switch generally takes effect January 1, and the 60 day employee notice window opens November 2. The paperwork is finalized before the notices go out. |
| Have a 401(k), considering a simpler plan | November 2 | The notice window for a January 1 switch opens; the old plan generally ends December 31. |
| Want a plan effective during the same year | October 1 | A SIMPLE IRA generally takes effect between January 1 and October 1, so same-year starts are decided by early fall. |
Why does November 2 matter for businesses switching retirement plans?
That date matters for every business changing something about an existing plan for the new year, and there are two common versions of it.
The first is the simplification switch: a business with a 401(k) considering a simpler arrangement. Under current rules, a SIMPLE IRA generally cannot coexist with a 401(k) in the same calendar year, so a switch means closing one plan at year end and opening the other on January 1. The 60 day employee notice window for a January 1 start opens on November 2.
The second is the upgrade switch, and it is the one we see most often right now: a business that has had the same SIMPLE plan with the same provider for many years, and the plan still works, but it is missing features that newer plan designs offer. The same November 2 notice logic generally applies, which means the decision and the paperwork happen in October, the notices go out in early November, and the new plan is live January 1 without the employees missing a single payroll contribution.
Either way, the paperwork is not the hard part. The calendar is. That is why we run the calendar for you.
Can a business switch retirement plan providers to add a Roth option?
Generally yes, and this is the feature pulling most of the upgrade switches we are working on this fall. Newer SIMPLE IRA designs can include a Roth contribution option, which gives each employee a choice in how they save: same contribution limit, two ways to save. Which way fits which person is a tax question, and that conversation belongs with a qualified tax professional. Our part is the plan design that puts the choice on the table at all, because an older plan that lacks the option makes the decision for everyone by default.
There is a second half to a well-run switch. The retirement money employees have already built up under the old plan does not have to be left scattered behind at the old provider. As part of the transition, existing balances can often be consolidated into individual retirement accounts, so each person ends up with their history in one place and their future contributions flowing into the new plan. Rules and timing requirements apply to those moves, which is exactly why the whole sequence gets mapped out in October rather than improvised in December.
A hypothetical, labeled as such, drawn from the shape of work we do every fall: a Central Pennsylvania business has run the same retirement plan with the same provider for over a decade. It works, but it has no Roth option, and several employees have asked for one. The owner decides in early October. The new plan paperwork is finalized before November 2, employee notices go out on schedule, the new plan is live January 1, and in the weeks that follow each employee's existing balance is consolidated into an IRA of their own. Nobody misses a contribution and nobody's money is left behind. This illustration is hypothetical and does not depict any actual business, client, or outcome.
What does a retirement plan cost a small employer?
Less than most owners assume, and federal law currently sweetens the math for businesses starting their first plan. Eligible employers who have not maintained a plan in recent years may qualify for startup tax credits that can offset much of the early cost, claimed on IRS Form 8881. The word "may" is doing real work in that sentence: eligibility depends on your headcount, your payroll, and your history, and a qualified tax professional is the right person to confirm what applies to you. Businesses switching an existing plan are generally playing for different stakes: better features, cleaner administration, and consolidated accounts, rather than credits. Our job is the plan design and the calendar. We are glad to sit at the same table as your accountant, and we often do.
What should an owner bring to a first conversation?
One document. If you have no plan, bring your payroll headcount. If you have a plan, bring its most recent statement or annual fee disclosure. From that, a good advisor can tell you in about 20 minutes which plan types fit, whether your current plan is missing features your employees would use, and what the honest tradeoffs are. If what you have is competitive and complete, we will tell you straight. Sometimes it is, and we will say so.
The real reason to decide now
The employee who asked the question in October will still be deciding where to work next year. In a labor market where employers from Mechanicsburg to Lancaster are competing hard for the same skilled people, the benefits line on your help-wanted ad is part of the wage. A retirement plan is how a 10 person company looks like a 100 person company to a good candidate, and a plan with modern features is how you keep the people who already know where everything is.
